It's sad isn't it. To change your on-line name you need to make a new profile, with the same set of buttons etc. For those who switch/are in clans (with rankings!) might be a big problem. But hey if they really thought about clans they would have included proper server administration

Yes i'm afraid so. The savegame folder has .profile files but theres only a bit of unreadable gibberish in it. Might just change the .profile name, but don't know where the buttons etc are stored
